Package: base-config Version: 2.08 Severity: important Tags: patch I've already sent a patch to debian-boot, but alioth continues down. This bug report for recording.
This bug is critical rather than important, but I record this as
important first.
Current base-config is unusable for Japanese, Korean, Chinese, Russian
or any other who uses special terminal.
Second stage will fill screen with unreadable glyph. Bad. This is
caused by two factor.
A. 2nd stage doesn't provide Framebuffer and terminal check routine is
corrupted, so special terminal (I recommend jfbterm) can't be used.
B. Moreover base-config don't do language fall back to English for
them, so unreadable glyph comes (it means symbol or control
characters are used. Of course this is unreadable and unmeaningful).
This patch fixes:
1. unset_lang_language unset LANG and LANGUAGES, but need to unset
LC_ALL (and maybe ENCODING) also.
2. prebaseconfig.udeb removed for inserting FB module. As Pere said,
base-config should cover it only if LANG needs (try_load_fb).
3. WRAPPER check routine is broken. New variable, WRAPPER_OPTION is
needed (Bug#225865).
4. When WRAPPER goes fail, LANGs which use special terminal should
unset its LANG (fall back to English).
5. Fix typo (small, but very critical) in jfbterm launch routine of
Japanese.
