A wrapper around libmount, for reading and manipulating filesystem tables.
A library for reading and manipulating filesystem tables, such as /etc/fstab.
It uses ctypes to wrap libmount, part of util-linux.
Every reading and manipulation of the filesystem table should take place in a with block to take the lock:
from libmount import FilesystemTable with FilesystemTable() as fstab: print fstab.target
A FilesystemTable acts like a list, so you can slice and iterate:
with FilesystemTable() as fstab: print [fs.source for fs in fstab] print fs[2:5]
FilesystemTable objects contain Filesystem objects, that each have source, target, fstab and options attributes. The first three are strings, whereas the latter is set-like:
with FilesystemTable() as fstab: fs = fstab # Will print e.g. "/dev/sda1 on / type ext4 (user_xattr)" print fs fs.source = '/dev/sda2' print "Options: %s" % ", ".join(fs.options) fs.options -= set(['user_xattr'])
To update the on-disk filesystem table, call save():
with FilesystemTable() as fstab: for fs in fstab: if fs.fstype in ('ext3', 'ext4'): fs.options.add('user_xattr') fstab.save()
It is not yet possible to add or remove entries. This has not been thoroughly tested when run by non-privileged users.
