I appreciate you taking the time to update this package; thanks!

Notice to everyone: After updating to 1.3, chkboot will warn you about changed hashes. This is because the hashing algorithm has been updated to use SHA512.

I'm going through your PR's. But please, don't advise anyone on using then, specially the EFI one.

A heads up for anyone trying to use this on an EFI system: Manually apply pull requests #9, #10, and #11 from github and it'll work perfectly.

Additionally, pull request #13 includes pacman hooks to automate the process when your boot images, systemd, or kernel microcode receive updates.

You're right, this hook has some limitations, specially regarding the usage of a EFI system partition as /boot. I am currently planning a complete revamp of this hook, including a merge with

It shouldn't be difficult to add a special case for an EFI system partition, since the UEFI specification determines it must be a FAT filesystem. As for the disk head, it backups the MBR, which on GPT is the protective MBR. Unless you are creating your GPT without it. Right now it backups 512 bytes. But that also backups the partition table, on a MBR disk. If you change your partitioning, it would trigger a false positive chkboot warning.

Thx for your great work man. My /boot is a FAT32 UEFI System partition on a disk with a GPT label. For this case, I have two suggestions:

1) The number of sectors of the stored disk head should be configurable, I use 34 to cover the entire GPT.

2) The inode and extent fileds in the boot file list don't make a lot of sense for a FAT filesystem, how about comparing the first x sectors of the partiton head holding the file allocation table?

Expect it to be updated today, at most tomorrow. I still haven't fixed all the bugs chkboot-git had.

Would have been nice to have this updated before deleting chkboot-git.

This is great, nice work!

Updated the package version function, thank you sekret.

In the future if anyone else would like to suggest changes/improvements, I invite you to do so on Github at

Hi, could you please use another pkgver function, which increments after new releases? I for example use

pkgver() {
cd "$_pkgname"
echo "$(git log -1 --format="%cd" --date=short | sed 's|-||g').$(git rev-list --count master)"

which right now produces

$ pacman -Qi chkboot-git | grep Version
Version : 20131209.22-1
