I come into forum as I ran into problem which I can not solve with help of existing materials in forums and wiki. I followed system recovery category but it didn't bring me solution for my issue.
I been running an installation of
homegear package which brings some additional kernel modules (libhomegear) which failed (maybe because) a dummy docker thing which acquired access to /lib, /log, and /etc directories (wrong form of docker volume mount). As a final result of these two actions I ended up with destabilized system where I could not execute any command (ie. ls command not found).
After restart my system shows boot manager, it begins to start up but fails to due to missing sbin/init:
ERROR: Boot device mounted successfully, but /sbin/init does not exist. Bailling out, you are on your own. Good luck. sh: can't access tty: job control turned off. [rootfs ]# _

After start from livecd I am able to mount system, however I can not run bash. All attempts which I made ends up with the same result. I used arch-chroot but it fails with same message.
chroot /mnt/manjaro chroot: failed to run command ‘/bin/bash’: Permission denied
File system is mounted properly (I adjusted fstab):
/dev/nvme0n1p7 on /mnt/manjaro type ext4 (rw,relatime) dev on /mnt/manjaro/dev type devtmpfs (rw,nosuid,relatime,size=7996912k,nr_inodes=1999228,mode=755) proc on /mnt/manjaro/proc type proc (rw,nosuid,nodev,noexec,relatime) sys on /mnt/manjaro/sys type sysfs (rw,nosuid,nodev,noexec,relatime)
The bash itself is executable:
[manjaro-gnome manjaro]# stat /mnt/manjaro/usr/bin/bash File: /mnt/manjaro/usr/bin/bash Size: 903440 Blocks: 1768 IO Block: 4096 regular file Device: 10307h/66311d Inode: 3147892 Links: 1 Access: (0755/-rwxr-xr-x) Uid: ( 0/ root) Gid: ( 0/ root) Access: 2019-11-20 12:14:38.180000545 +0000 Modify: 2019-09-03 19:27:18.000000000 +0000 Change: 2019-11-20 12:14:31.853333873 +0000 Birth: 2019-10-14 14:36:34.492363214 +0000
I can run program with no issues so its not a problem of noexec or anything like that. I failed to obtain any knowledge (so far) on how to fix chroot issue. I execute it as a root user thus I expect that it should work with no issues.
I need to get into chroot to run
mkinitcpio. Thank you in advance for your answers.
