# restrict size (computed and absolute!) to maximally this limit
|
|
# can be set to empty for no limit, but beware of filled partitions!
|
|
# this is/was a (outdated?) 32bit kernel limit (in MBytes), do not overrun it
|
|
# but is also sensible on 64bit to prevent filling /var or even / partition
