The stat(3) and access(3) are in this case almost interchangeable, so choose
the lightweight function with additional advantage checking the file is
executable.

The libmount provides way how to deal with parsing errors in fstab --
on error callback function is executed and according to the return
libmount manipulate with the malformed line, possible are three
states:
1/ fatal error; all file ignored (callback rc < 0)
2/ recoverable error; malformed line ignored (callback rc > 0)
3/ ignore the error (callback rc == 0)
The 2/ is the default if no callback specified.
Unfortunately our utils uses 3/. The correct way is to use 2/.

There two possible ways, print error and exit on too long names or
truncate the filename -- but it's impossible to do both in the same
code :-) It seems that code already assumes warning on long names, so
let's remove errx() and keep the behavior in dependence on -E.

braces that cause reader to wonder if test is meant or not, squeeze error
code list, move references to bottom of the manual, and use mail or web

Earlier user could define more blocks than device, or backing file for
loopback file system, had available. That lead to a system crash with
following commands;
fallocate --length 64KiB test-file
mkfs.minix -3 -i 842160 test-file 104882174
mkdir test-file.d
mount test-file test-file.d
cp /etc/service test-file.d
Killed
sudo umount test-file.d
The minix driver should probably not hang the whole kernel, but the least
that mkfs.minix ought to do is not to let users to get that condition
quite as easily.

Checks about inodes vs block sizes does not add much robustness. Both
values are derived at compilation time from struct minix_inode size, and
they form full definition circle.
Bad block check for none-block devices should not be supressed, user
requested it so let him have it.
Check for st_rdev == 0x0300 || st_rdev == 0x0340 was unreachable.

mkfs.minix misbehaves when attempting to create a large v2 or v3
filesystem. I finally traced it down to attempting to create too many
inodes so that the first zone is past 65535 blocks in. This obviously
doesn't work as the on-disk superblock says this is a 16 bit integer.
I wrote a patch that catches this, clamps to the absolute v2/v3 limit
(like it already does for v1), and sets the blocks per inode to a more
reasonable ratio when exceeding half a gigabyte. Having a half-gig
filesystem with most files being smaller than 3k isn't really reasonable.
I suppose if you don't want to adjust inode sizes automatically you could
take that part out, and it will just crab sooner.
Given the non-attention in the code, I suspect nobody ever had cause to
try such a big minix filesystem. Well I have my reasons involving some
deeply embedded work where ext2 would place too much strain on the
hardware.
