經Wubi安裝的ubuntu,更改”/host” permission的方法

經wubi安裝後的ubuntu, /host原設定為root所擁有(ownership), 而/host本身是ntfs格式(windows的關係)。
chmod後,從開也會不見，所以要更改/host 就要作以下動作。

原文如下:

The mounting for /host is done in the initramfs, which makes this tricky
(for me anyway) to track down. I’ve found a workaround for the problem:

Edit /usr/share/initramfs-tools/scripts/local-premount/root_locale

Append ,umask=022 to this line:

echo ROOTFLAGS=\”${ROOTFLAGS}locale=$ROOT_LOCALE\” >>
/conf/param.conf

so that it reads:

echo ROOTFLAGS=\”${ROOTFLAGS}locale=$ROOT_LOCALE,umask=022\” >>
/conf/param.conf

Save, run:

update-initramfs -k all -u

Reboot. /host will now be 755.
