[Freeipmi-devel] [PATCH: freeipmi] get_home_directory ()

[Anand Avati]

Hi,
this is an enhancement patch to fish to use /tmp/user
in case $HOME is not available.

-- ChangeLog --

* fish/src/fi-util.c: get_home_directory () creates and returns
  /tmp/user in case pwent->pw_dir is not present/writable

--

regards,
avati
