comment How to configure GRUB to load Windows 7 Install in UEFI mode
@mikeserv, Sure, you could manually move partitions around, add an EFI system partition and swap out the boot loader rather than simply reinstall it right in the first place, though this would still require the use of some sort of live media. That doesn't make the answer "wrong in almost every sense". Also while you might make the pedantic argument that I should have said "configure your system firmware to boot in EFI mode", most people understand the word BIOS better, and it is commonly used in that generic sense of system firmware rather than specifically referring to the IBM PC BIOS.

comment Does Grub2 support putting /boot on a RAID5 partition?
You can not use LILO to boot from a raid5 no matter what metadata format you use.

comment umount /home does not work
@sgmart, no, you go to single user mode either by using the 's' option when booting up, or init s or shutdown. Ctrl-alt-F1 just switches to the first text mode virtual terminal. I believe mint, like ubuntu, has the root account locked by default so this is the only way to log in as root ( you can't login as root on a virtual tty when not in single user mode ).

comment What filesystem metadata operations are actually journaled in ext4 & xfs?
@naelyn, oh yea... good point... might need to ask about that one on the linux-fsdevel mailing list... with hard links I believe you open and sync the directory containing it, maybe symlinks work the same?

@naelyn, an fsync() will flush all blocks related to a file, including a non fast symlink.

comment Is it useful to setup RAID0 on laptop?
The speeds of the drives are more or less added.. whether that is worth it or not is a matter of opinion.

comment Does tar actually compress files, or just group them together?
Actually an empty file will not consume 1kb. A 1-1023 byte file will.

comment What does exit 99 means?
@mikeserv, properly written scripts use set -e to enable error checking so you don't have to test every exit status yourself. Any program you call that returns non zero will be treated as an error and cause the script to abort. make will also automatically stop the build and report an error if it calls something that returns non zero, again, without you needing to explicitly test the value. In fact, your [ $? -eq 99 ] returns 0 for success and 1 for failure.

comment Large ext4 partition ridiculously slow when writing
@HaukeLaging, you got that backwards; -t flushes the kernel cache and actually measures the disk's real read speed, -T just reads what is already in the kernel cache.

comment What determines the maximum file size in ext2 file system
This limit was also overcome ages ago by the use of a flag in the inode that indicates that the i_blocks value is, in fact, in units of block size rather than 512 bytes. The triple indirect block structure though, can only address just over 4 TiB using a 4k block size.

comment What does exit 99 means?
They know it means failure because that is the convention for exit status: anything other than zero means something went wrong. The specifics of what what went wrong ( and this may be very minor and something you may want to ignore if you know the specifics ) are up to the application.

comment What does exit 99 means?
The shell, and most other tools, including make, treat any non zero exit value as an error.

comment How can I find out about “rootfs”
On debian, /etc/mtab is a symlink to /proc/mounts. Otherwise, you would not see the rootfs at all.

comment What does exit 99 means?
Not quite - 99 is not zero, and so indicates that the program failed for some reason.
