That might make sense, as I created this container through
debootstrapping the filesystem into
/home/osmium/.local/share/lxc/osmium/rootfs and then chown/grping all
the files to the appropriate users in this user's subuid/gid range...
pasted below in case anyone finds it useful. Please let me know if there
are further steps required to make this template/container valid.
Incidentally, I just fixed the "invalid mount point" warnings, they were
just the LXC mount paths not being complete.
$ cat shift_chid.py
path = sys.argv
offset = int(sys.argv)
def logic(path, offset):
stat = os.lstat(path)
o_u = stat.st_uid
o_g = stat.st_gid
n_u = o_u + offset
n_g = o_g + offset
return(path, o_u, o_g, n_u, n_g)
def report(path, offset):
print("Path: %s. Current UID/GID: %s/%s. Proposed UID/GID: %s/%s."
% logic(path, offset))
def chid(path, offset):
p, _, _, u, g = logic(path, offset)
os.lchown(path, u, g)
def verbose(path, offset):
for cur, dirs, files in os.walk(path):
for x in files:
verbose(os.path.join(cur, x), offset)
except Exception as E:
sys.stderr.write("Error reported: %s" % E)
