[SOLVED] Help with executing scripts in a mount using arch-chroot

TheWingedHussar · 2022-05-19 01:45:14

I'm attempting to install arch using a bash script.
Problem is, when i run:

"arch-chroot /mnt $HOME/HussarInstaller/scripts/sysconf.sh",

or any script with arch-chroot, it returns:

"chroot: failed to run command ‘/root/HussarInstaller/scripts/sysconf.sh’: Permission denied".

I've consulted the wiki and followed its instruction remount with the execute permission, so i ran the following but retried to no avail:

"mount -o remount,exec /mnt"

Further searching online showed up nothing.

Wiki Page im refrencing:
https://wiki.archlinux.org/title/Chroot#Using_chroot

Full Script:
https://github.com/ThePolishHussar/HussarInstaller

Thanks in advance for any help!

What does `ls -l /mnt/root/HussarInstaller/scripts/` give you?

Just do something like

cp sysconf.sh /mnt
arch-chroot /mnt
./sysconf.sh

Just remember that the script will be run as root, so $HOME will be mapped to /root.
The first line of the script (the sourcing part) will not work unless you copy that to /mnt/root/HussarInstaller/install.conf
I'd also strongly recommend bringing this up with the author of the script on github.

They *are* the author, and sourcing other files is not an issue. If they were trying to use someone else's script, that would be off topic here.

"What does `ls -a /mnt/root/HussarInstaller/scripts/` give you?":

at the time the scripts are refrenced:
customize.sh install.sh packages.sh partions.sh sysconf.sh system_services.sh

"cp sysconf.sh /mnt
arch-chroot /mnt
./sysconf.sh"

arch-chroot will just chroot and ask for manual input, wont work

"Just remember that the script will be run as root, so $HOME will be mapped to /root.

Ive taken this into account, any scripts run using arch-chroot sources the config file using:
"source $HOME/HussarInstaller/install.conf"

My apologies, I realized I typoed and corrected it as you were replying. I as actually looking for ls -l, not ls -a.

Oh. I also didn't notice that they copied the whole folder into the chroot. My bad

Source (normal root):
-rwxrwxrwx 1 root root 160 May 18 21:06 customize.sh
-rwxrwxrwx 1 root root 417 May 18 21:06 install.sh
-rwxrwxrwx 1 root root 1136 May 18 21:06 packages.sh
-rwxrwxrwx 1 root root 1222 May 18 21:06 partions.sh
-rwxrwxrwx 1 root root 1614 May 18 21:06 sysconf.sh
-rwxrwxrwx 1 root root 302 May 18 21:06 system_services.sh

Coppied (/mnt/root/):
-rw-r--r-- 1 root root 160 May 18 22:11 customize.sh
-rw-r--r-- 1 root root 417 May 18 22:11 install.sh
-rw-r--r-- 1 root root 1136 May 18 22:11 packages.sh
-rw-r--r-- 1 root root 1222 May 18 22:11 partions.sh
-rw-r--r-- 1 root root 1614 May 18 22:11 sysconf.sh
-rw-r--r-- 1 root root 302 May 18 22:11 system_services.sh

I assume i need to add some flag to the cp command to keep these permissions in the copy. Which would that be?

Try --preserve=mode.
If that does not work for you try the install command with the -m flag instead of cp (look into the man page to see how install works).

Please use code tags, https://bbs.archlinux.org/help.php#bbcode
Then try

arch-chroot /mnt /bin/sh -c 'echo snafu'

Didn't try either, opted to use

chmod a+rwx /mnt/root/HussarInstaller/scripts*

So you simply lacked permissions on the scripts directory?

after i coppied them into the mounted system that was the case.

"cp -a" will preserve attributes
Is this the original situation or an effort to solve it following post #3 ?
