Following a poll in last week's IT Manager Update newsletter, a number of readers have written in with their tips and opinions about dual booting Linux and Windows operating systems.
Sam Johnston, director at Australian Online Solutions, said that he supports anything which helps with the introduction of Linux into businesses. "Having just wasted 15 minutes of my day trying to reactivate Office XP Professional after moving to a RAID boot disk I certainly appreciate the freedom OSS offers," Johnston said.
Johnston believes that the startup process still takes way too long, especially at the BIOS stage, which he finds annoying given that most of the work done by the BIOS is redone by the PnP operating systems.
"Efforts to replace the BIOS with the Linux kernel certainly have my attention, as boot times as short as three seconds have been recorded," Johnston said. "As such, minimising the number of reboot cycles is important. Also, users are likely to be more productive if their machines stay up (ie, don't crash and need to be rebooted to accomplish different functions)."
Johnston said there are a number of options for providing access to both operating systems, including Cygwin libraries which provide a Unix environment within Windows, a virtual machine approach, or by operating a remote desktop.
Although project leader Matt Tavani doesn't use dual boot at all at the organisation he works for, he said that with the integration of two departments earlier this year, the IT department was now faced with the prospect of having a couple of hundred Windows 95 and Windows 98 boxes, on what had previously been a pure Windows 2000 network.
"Not only has this caused headaches for the IT department, but also for users who are forced to migrate between sysetems if they transfer divisions [or] roles into an area which is managed by the other merged group," he said.
Tavani believes that both business managers and the IT department need to be involved in deciding whether or not the organisation opts for dual boot.
"Those kinds of decisions can't be made in isolation and usually lead to angst if IT rejects it out of hand, or a rogue business manager gets one of their own people to install it by stealth," he said. "The business owner should have a legitimate business need--and not just because it is cool--and the IT department need to recognise that just saying 'no' doesn't always work either."
An IT division should assess this on the merits of the case, and provide agreed service levels to the business unit which has the dual boot requirement, he argues.
"This way the business owner can get on with their work, and the IT department knows it does not have to service the entire organisation as dual boot," Tavani said. "If all of a sudden, or even over time, the rest of the organisation needs such functionality then it gets worked into the next round of IT planning, which means it can get planned for, budgeted and staffed to support."
Another respondent to the IT Manager poll said that in his experience managers do not have the technical knowledge to accurately assess what is better for business when it comes to a technical solution.
"I believe that the selection process needs to go something like line management--the direction is provided by the top, the familiarity and input on experiences provided by the bottom and the IT professionals provide the recommendations on the workable solutions."
Nor does everyone believe that dual boot is necessarily the answer for organisations. Although Daniel McHugh, research analyst of IT trends at Gartner Asia Pacific, believes that in certain cases it could be warranted, he believes that dual boot from a desktop point-of-view increases the complexity of management.
McHugh also said that in an enterprise environment It would increase the overall total cost of ownership to run dual boot on all desktops. "I can see the situation if someone was migrating from a Windows environment to a Linux environment that they might want some level of stop gap...where users could be proactively moved across," he said. The use of dual boot within organisations also won't necessarily increase over time, McHugh said.

In disagreement with the Gartner staffer, let me outline the business advantages and disadvantages of rolling out dual-boot Linux and Windows workstations.
Disadvantages:
1) some effort is involved in including Linux in your desktop SOE ghosting image
2) need for some IT staff who know Linux as well as some staff who only know Windows.
Realizations:
1) That the cost of including Linux in your desktop SOE builds is trivial. Cost of deploying Linux is even less so
2) that by having an increasing number of your non-IT staff be Linux-aware, you are in a better position to move towards Linux in an accelerated pace in future, if business or technical reasosns dicatate this course of action. This is purely a case of not putting all your eggs in one basket(**** a management principle that most of us understand. The increase in staffing flexibility is another business advantage.
Advantages:
1) that you will gain the equivalent of $10,000 per workstation of software on the Linux partition (from office suites, multi-media apps through to developer tools)
2) That you can slowly bring your staff up to some level of familiarisation with Linux desktops.
This last point is a substantial business positive, as it means that you slowly, inexorably regain control of your own businesses IT destiny. This is because you can finally be offered a choice as to which business desktop you want to continue using. If Microsoft decide to raise software prices on you, you can have an 'escape route'.
