/usr/java/lib/fonts is readonly

[mimihuhu]

I update my Kindle Touch to 5.3.2.1, and jailbreak it.

I don't like the default font for Asian characters, so I want to post some new fonts into folder "/usr/java/lib/fonts", and re-generate "fonts.dir" and re-config "local.conf". In that way, Asian characters can be displayed as new font, and Latin characters can be displayed as original font. But I notice folder /usr/java/lib/fonts is no longer a read-write folder now, even after running comand "mntroot rw". Seems some new restrictions are added to prevent making changes to this folder.

I know how to use an alternate font by adding empty file "USE_ALT_FONTS" and putting font files into folder "fonts" to device in USB mode. However, if I change a font in this way and read a book with an Asian font, the Asian characters will be pretty, but the English characters in that book will also displayed in Asian font, and will be ugly.

Does anyone know how to mount /usr/java/lib/fonts as a read-write folder? Thanks!

the mntroot script only affects the file system mounted on '/' (root filesystem).

/usr/java/lib/fonts may not be on that same file system.

hmm...
Lots of ways you could learn what file system that path is on.
For a *nix newbie, perhaps the easiest is to post the output of the 'mount' command. Let us read it back to you.
Just enter:
mount
at the Kindle command line, cut and paste the report in a code block of your next post.

/dev/loop/4 on /usr/java/lib/fonts type cramfs (ro,noatime,nodiratime)

rebuild the cramfs.

Among others... not mega tough to do. Knc1 has explained the process more than once on many threads. good luck

@mimihuhu

the font config i used changes the Chinese fonts without affecting the original English fonts. you may want to give it a try. the font config can be found in
