php-chroots.target subsequent targets not active

[TCB13]

Hi!

Thank you very much for your two very detailed articles and script on how to setup the chroots for PHP. I've been using this in low power ARM devices where I "can't" run docker/lxc/systemd-nspawn due to RAM limitations.

Now, over the years I've noticed a small glitch in the script that I never come around to fix. It appears that whenever I reboot the system php-chroots.target is reached however the subsequent targets aren't usually reached.

After rebooting here is what happened:

root@hostname:~# systemctl status php-chroots.target
● php-chroots.target - Bind all binds for all PHP-FPM chroots
   Loaded: loaded (/etc/systemd/system/php-chroots.target; enabled; vendor preset: enabled)
   Active: active since Sat 2020-11-07 19:20:14 UTC; 37s ago

root@hostname:~# ./web/php-chroot-bind status
Chroot: /mnt/NVME1/web/test_chroot/chroot
        - /usr/share/zoneinfo
        - /dev/urandom
        - /dev/zero
        - /dev/null
        - /etc/resolv.conf
        - /etc/hosts
        - /lib/aarch64-linux-gnu/libnss_dns.so.2
        - /usr/share/ca-certificates
        - /etc/ssl/certs

Now the test_chroot:

root@hostname:~# systemctl status php-chroot-mnt-NVME1-web-test_chroot-chroot.target
● php-chroot-mnt-NVME1-web-test_chroot-chroot.target - Bind all binds for PHP-FPM chroot /mnt/NVME1/web/test_chroot/chroot
   Loaded: loaded (/etc/systemd/system/php-chroot-mnt-NVME1-web-test_chroot-chroot.target; static; vendor preset: enabled)
   Active: inactive (dead)

As you can see php-chroots.target is loaded and active, and then php-chroot-mnt-NVME1-web-test_chroot-chroot.target is inactive.

To fix this, I just need to issue:

systemctl start php-chroots.target

And then all chroots get to work just fine. Any idea why this would be happening? I've also noticed that sometimes some of the other chroots start others don't. It seems random.

I have same problem, my OS: debian 10.7 x86_64 SMP Debian 4.19.160-2 (2020-11-28) x86_64 GNU/Linux

comment the script line : 82 and 83 using "#"

Requires=php-chroot-create-mountpoint-file-${eBind}@${eChroot}.service

Requires=php-chroot-create-mountpoint-dir-${eBind}@${eChroot}.service

It's work fine on my system, reboot will auto re-mount files/dir

Because when using command: php-chroot-bind bind will auto create empty file and dir.

you can use "sudo journalctl -b -0" check the systemd log, you will found some line like "Create mountpoint (dir) for xxxxxxxxxx in PHP-FPM Chroot skiped"

the php-chroot-create-mountpoint-file-${eBind}@${eChroot}.service file will check dir/file exits, if dir/file exits = true , it will skip the mount command. so reboot can't re-mount file / dir.

my english no good, Hope you can understand
