Debian sistemimde, /
ayrı bir bölümüm var ve monte ettim read-only
. Sadece /home/
, /var/
ve /tmp/
yazılabilir bulunmaktadır. Ben de bir oluşturduk Pre-Invoke
ve Post-Invoke
apt hook
böylece apt
paketlerinin yüklendiğini veya yükseltilmiş ve geri yeniden bağlayın olan yazma için yeniden bağlama sistemi otomatik can read-only
zaman bitmiş:
DPkg::Pre-Invoke {"mount -o remount,rw / ;};
DPkg::Post-Invoke {"mount -o remount / ;};
Tüm kurulum tek bir istisna dışında iyi çalışır. Bazen yükleme / yükseltme işlemi sırasında bazı servisler yeniden başlatılmalı veya kısa pencerede takıldığımda yeni dosyalar /
açılmalıdır read-write
, bu dosyalar write
izinlerle açılır . Yükleme / Yükseltme tamamlandıktan sonra, benim Post-Invoke
kanca döner hata değil remount can çünkü /
geri read-only
.
Bu sorunu çözmenin bir yolu var mı? Bu çok sinir bozucu, çünkü bu durumda genellikle sunucuyu yeniden başlatmam gerekir, ki bu pratik değildir.
