fdisk: use more readable "GPT" name rather than "EFI GPT"
Although GPT is defined in EFI spec, it is widely used without EFI, as it
reserves space for the MBR and works fine on PC/BIOS systems provided the
bootloader supports it.
This is in fact the way everyone seems to be following to overcome the 2 TiB
limitation with MSDOS partition table.

mkswap: set UUID for swap space (add -U option)
A friend of mine is looking into the possibility of cloning Debian
(and other) systems automatically and stomped over swap partitions
getting assigned new UUIDs every time the new harddisk is partitioned
and swap is created.
It's essential when partitions are to be recognised by their uuid and
not by their old device path anymore.

mount: "can't create lock file" message sometimes means failure, sometimes not
What the patch does is goes from the situation where:
1) If /etc/mtab doesn't exist and /etc is read-only, you get the
"can't create lock file" message and the mount fails
2) If /etc/mtab does exist and /etc is read-only,you get the same
message but the mount succeeds
Clearly, the failure to update /etc/mtab should either cause the mount
to fail or not ... sometimes causing it to fail, and sometimes not
(each with the same message) is not useful.
This patch sets the same behaviour for create and update mtab. In both
cases it prints error message and the mount succeeds.

rtcwake: fix UTC time usage
Timezone handling is broken in this version since it's always
passing UTC time into the kernel, even on systems where the
RTC uses the local timezone.
I think that bug must come from bugs in how the system used to
to originally develop this code handled the RTC timezone. Both
RTCs should have been kept in UTC ... but only one of them was.

losetup: support unlimited number of loops
Old implementation:
- supports 256 loop devices only
- doesn't support gaps in list of loop devices
(e.g. loop0, loop1, loop3 -- loop3 is invisible)
Kernel 2.6.21 removes artificial maximum 256 loop device. Now the maximum
of loop devices could be really huge (depends on limit of MINOR
numbers). It means we need a better way how work with loop devices
than blindly call stat(2) for all 0-1048575 devices.
This patch uses three methods:
a) scan /sys/block/loopN (used for losetup -a only). This method is
probably the fastest way how found used loop device on machine with
huge number of devices in /dev.
b) classic way, stat(2) for all loop[0-7] devices (default number of
loop devices). This cheap method is sufficient for 99% of all machines.

Unfortunately, it'll only cope if the error it gets is ENOENT (i.e. the device

error is ENODEV, which is what happens when the device node exists, but there's

rtcwake: misc cleanups
Cleanups for rtcwake:
- Minor doc updates: highlight the framebuffer problem,
give correct history of this code
- Improve debug output
- Fix some linelength bugs
Note that this code predated the sysfs "wakealarm" mechanism, and
works around several now-fixed bugs in the kernel RTC framework.
Nowadays it would make sense to make this program use only the sysfs
interface to the RTC, using "since_epoch" instead of RTC_RD_TIME and
"wakealarm" instead of the four other ioctls. That could simplify
the mess involved in timezone handling.
