See TMPFS_SIZE in /etc/defaults/tmpfs And it'll cheerfully use swap, so just make sure you have enough swap for your use case, and set the limit to suit your needs. Alternatively, you can always create a new temporary location where you have enough space (i.e. ~/.tmp/ ) and then either set TMPDIR to that in the relevant user's shell profile/rc or define an alias such as: alias debdiff="TMPDIR=~/.debdiff-scratch-space debdiff" Cheers, Phil. -- |)| Philip Hands [+44 (0)20 8530 9560] HANDS.COM Ltd. |-| http://www.hands.com/ http://ftp.uk.debian.org/ |(| Hugo-Klemm-Strasse 34, 21075 Hamburg, GERMANY
