Your argument style is very strange. You say Windows behaves horribly so
we should expect Linux to behave that way as well. And then you minimize
the problem.
What?? I said that they had to go down for hours every night at 3AM. So,
20-30 seconds of annoyance, once in a blue moon if you use ext4, is our
tradeoff for file system maintenance.
It is a valid concern, and the answer is neither to give up on Linux, or
to just say "suck it up". It is to make systemd as responsive and
configurable as one can.
Horse apples. fsck has been with us since the dawn of UNIX (1). Are you
saying that after almost every file has been wiped and replaced by a
dist-upgrade from wheezy to jessie, where it is almost a guarantee that
every file size has changed, that an fsck ISN'T in order after the file
system took that MASSIVE pounding?? I would think that if it didn't
happen someone would take a drubbing. I fail to see where systemd is
even an issue here. So, the average Joe or Jane Lunchbucket Debian user
should be able to cntl C the process that might save his file system??
And, that we need more complexity?
Again, every google search on "interrupt fsck" said "Don't Do It!"
Where's the beef?? "A rule of thumb, automate where you can make
mistakes."
" Faster file system checking
In ext4, unallocated block groups and sections of the inode table
are marked as such. This enables e2fsck to skip them entirely on a check
and greatly reduces the time it takes to check a file system of the size
ext4 is built to support."

There ya have it.
Use ext4 (or ZFS with scrub, which is run on a live file system).
Automate where you can make mistakes.
Don't interrupt fsck. If it is forced to run, it knows better than you
why. :) Ric
