Probably the expectation is that you would recover those files from vi and discard them if you don't want them.

From the File Hierarchy Standard (2.3): I am going to disagree with my esteemed colleague and say yes, with restrictions. Are you the only person using your computer? If so then you can only hurt yourself. If the answer is that this is a multiuser machine, say a university or large corporate business machine, then no. You might be killing off someone else's work. But if it is your own machine then fine. > |/var/tmp : Temporary files preserved between system reboots > | > |Purpose > | > |The /var/tmp directory is made available for programs that > |requiretemporary files or directories that are preserved between system > |reboots.

But the administrator of the machine is allowed to set local policies which override the FHS.

One example is the one which started this. 'nvi' is one which expects /var/tmp/vi.recover to be persistent across a reboot. But a reasonable site-specific policy could be to delete files older than a week. The 'tmpreaper' package provides this for Debian. It is a fork of the Red hat 'tmpwatcher' package. apt-cache show tmpreaper apt-get install tmpreaper Then modify /etc/tmpreaper.conf for something like the following. Use your own site-specific policy here. TMPREAPER_TIME=7d TMPREAPER_DIRS='/tmp/. /var/tmp/.' Bob
