I confirm this is a known issue with vt(4): it uses a callout to refresh the screen, but for reasons unknown to me, the callout is not called anymore on mountroot prompt. I tried to debug this but failed. Since then, I didn't have time to work on this again. So maybe callouts are disabled in this situation. If there is a way to detect that, then vt(4) can go back to a "synchronous mode" where it refreshes the screen after each typed character, like it does when ddb is active. I will repeat this in the bug report. --=20 Jean-S=E9bastien P=E9dron --AXlQFSuSJxW4vmkjT4whgfo7VNcrsdjhk-- --0B9JVUCBwOKSP9m8Kq0FVuC4PHAci9EkL Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQJ8BAEBCgBmBQJW8pZUXxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXQ2NzA4N0ZEMUFFQUUwRTEyREJDNkE2RjAz OUU5OTc2MUE1RkQ5NENDAAoJEDnpl2Gl/ZTMAHwP/RqsOpvumSYEqUIiSSQTIu5w pRmrdg77PhVHRDk627QbA/IEP3o4hrkSZUEwDcEkzDsIu1cNY8vrJVOwPtQmhH3T XFl+s8SbByJLDv65l3RRGh4bRdEbi2otojG1xN40rRfQKEq7S3pt+94olg9eFr+k 8NiQiIueqmt7KVtjowrRwMRxV4lnfqUmo9IDsu9VxOZIp2wsNh3wvZ64zcSDq5nu gV4edAyLdjikQDrc9SB5tbZYcUx26is4hYWY/UyHyNiuuLGw65zL1wYXuWkjC0Uf z+wZhzBl4wCNUmaJ0zlOh91+QveGdnIzipQGJaEqeee2l8IUNthwpexnHBcRGSrD FZerOFYNv0cvR624k1d0u9e9e41oxLejYruiut5vN6s7xIzPRWHD0HQgtrEW9Odd UyW9tD1+4NMtItbCYQKXNvDyYfgadDF50qKUwUFC52Z49o5Bf1w2HMtaIHwmWKjZ mbIrQweuDfew3DiEoFEJG773WvzX2OnZFJqjUbfLVQFMpYkNWQVJgRwXDxSQvQcz VVRU7lPGgDx4rLT3gqo49oThqigJOZXFljYXTBRcPlzQnNsyHPPHCkYd7GaKQnK9 UaKbLuRNJI2a02G3mENGVhDaqPVbYbkNW2Eu7XJc+N+yl4vS5is6SN0koJfEqRpx Drd85vptITNp6pqq6oh5 =NZuA -----END PGP SIGNATURE----- --0B9JVUCBwOKSP9m8Kq0FVuC4PHAci9EkL--
