When device names are long (more than 20 characters), the
df test will fail with an exception:
self.assertTrue(int(output)>5120, msg=msg)
ValueError: invalid literal for int() with base 10: ''
at least when busybox is in use.
The reason is that busybox breaks the line in that case:
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/disk/by-partuuid/8e991e5a-cebd-4f88-9494-c9db4f30cb02
1998672 87024 1790408 5% /
and the code tries to extract the fourth field from the
second line, which is empty of course.
df can be told not to break lines, though, using the -P
flag, which turns on the POSIX output format, and is
supported by busybox df and coreutils df:
Filesystem 1024-blocks Used Available Capacity Mounted on
/dev/disk/by-partuuid/8e991e5a-cebd-4f88-9494-c9db4f30cb02 1998672 87024 1790408 5% /
