PKGBUILD backup=() files removed on uninstall [SOLVED]

JesseSteele · 2024-08-02 22:31:24

I've ready through the Arch PKGBUILD wiki ad nausium, and nothing works.

Everything installs correctly, the service works, everything runs...

But, then when I uninstall with `sudo pacman -R myapp`, the `/etc/myapp/conf` file and directory still get deleted! I want to keep that `/etc/` config unless I use `sudo pacman -Rsn myapp`. What am I doing wrong?

Here is my PKGBUILD:

pkgname=myapp
pkgver=1.0.0
pkgrel=1
pkgdesc="world's most amazing app"
arch=('any')
license=('GPL')
depends=('systemd')
source=("$pkgname.sh" "$pkgname.service" "conf")
sha256sums=('SKIP' 'SKIP' 'SKIP')
backup=('etc/myapp/conf')

package() {

  install -Dm755 "$srcdir/$pkgname.sh" "$pkgdir/usr/lib/$pkgname/$pkgname.sh"
  install -Dm644 "$srcdir/$pkgname.service" "$pkgdir/usr/lib/systemd/system/$pkgname.service"
  install -Dm644 "$srcdir/conf" "$pkgdir/etc/$pkgname/conf"
  
}

Included files that work (FYR)

├─ PKGBUILD
├─ conf
├─ myapp.service
└─ myapp.sh

Pacnew_and_Pacsave#.pacsave Was the removed backup file modified from the one that was installed by pacman?

Both of these return nothing of that file:

# find /etc -name '*.pacnew' -o -name '*.pacsave'
$ grep '\.pacnew\|\.pacsave' /var/log/pacman.log

Even beyond that, I want the file and directory `/etc/myapp/conf` to remain in place, right where it is. Can that be done when installing with `makepkg`?

Yes it can be achieved by not having `/etc/myapp/conf` be part of the package but installed by the .install script or an alpm-hook. This would not be following Arch package guidelines though which is only to preserve modified config files.

If preserving the config file in `/etc/` can only be done against guidelines, should I make a feature request?

What is the use case for the unmodified config file after package removal? You could make a feature request to the pacman project to support it. You could submit an idea covering the change in the handling config files you want to see.

A feature request for something totally useless will just be ignored. If you modify the file, it already gets saved. If it's not modified, there is no point in saving it.

I want to keep that `/etc/` config

Why do you think you want to preserve a default file? What's the actual problem/task/goal?

Sorry all, I did not understand the description from the backup section. Files must be changed for the backup array to have any effect. I added a brief clarification to prevent such a misunderstanding, also addressing directories. Thanks, my question is answered.
