[PATCH 1/1] do not print warning about missing home directory in chroot

[Date Prev] [Date Next] [Thread Prev] [Thread Next] [Date Index] [Thread Index]

 



From: Christian Hesse <mail@xxxxxxxx>

Since setting options.chroot_directory to NULL after successful chroot
the following error message is back:

Could not chdir to home directory /home/user: No such file or
directory

Remember that we are inside a chroot and do not print error message
about missing home directory.
