I've faced this problem throughout my entire career.Either there were no Linux servers (OK I know a lot runs on Linuxbut you don't do much on an esx host or some other similar box/appliance, for example, nor do you want to) in the environment or they were off-limits.I know the answer is to find a place with mixed Win/Linux environment like 70/30 or better but it seems they want people with both skills already and often are not willing to compromise.Anyone have any tips to share? Unlike with Windows, I can't even fall back to an entry-level position to get professional experience of Linux.I've even worked jobs where they told me I'd get exposure, I thought I was going into a mixed-mode environment and it was a flat out lie!
