This allows copying in arbitrary file systems on the block level into
newly created partitions.
Usecase: simple replicating OS installers or OS image builders.
Strictly speaking this is a compat breakage, but given the tool was
added only in the last release, let's try to sail under the radar, and
fix this early before anyone notices it wasn't supported always.
This is a follow-up for 9f83091e3c.
Instead of reading the mtime off the configuration files after reading,
let's do so before reading, but with the fd we read the data from. This
is not only cleaner (as it allows us to save one stat()), but also has
the benefit that we'll detect changes that happen while we read the
files.
This also reworks unit file drop-ins to use the common code for
determining drop-in mtime, instead of reading system clock for that.
This adds --empty=create and --size= for creating loopback files from
scratch of a specified size, or growing loopback files to the specified
size when they already exist.
This is useful when operating on disk image files, as a manual
invocation of fallocate(1) becomes unnecessary.
The enum used for column names is integer type while table_set_display() is parsing
arguments on size_t alignment which may result in assert in table_set_display() if
the size between types missmatch. This patch cast the enums to size_t.
It also fixes all other occurences for table_set_display() and
table_set_sort().
